[PRad] repetition for collaboration meeting

Tue Nov 1 16:21:52 EDT 2016

Hi Kondo,

For you 2) question, using your terminology, The results on the plot is
sigma_resolution = sigma_residual / sqrt 2, assuming two gems having same
resolution. We just removed the statistical box that ROOT inserted from the
plot. Maybe we can discuss more during Maxime's practice run.

Best,
Xinzhan
